Live Line Insulators 

Polymeric Long rod strain and post insulators

11KV – 420KV

Strain and post insulators are necessary with all overhead lines, as well as substation installations.  Over the past twenty years, the designs of these insulators have greatly changed with the introduction of new materials, such as silicon and composite materials, replacing traditional porcelain. The new designs can achieve greater mechanical strength with less weight, making installation easier:


  • Light and compact designs

  • Extremely high strength requirements

  • Very long spans

  • Elevated conductor suspension points

  • Special string configurations

  • Extreme ambient conditions

  • Special designs on request
